relax everyone im here lol well 1st of all i got bondies hotdog that he swore was the most horrible thing out. im sorry bondie but it was a really nice sound. less drone than stock but more meat, but wasnt really much louder SO i went back to drew and got straightpipe instead. the result: VERY NICE!! probly the best sound your going to get out of the aurion. has got a tiny little bit more drone than stock resinator but it sounds really tough up in the revs, purrs nicely on the highway too. but not yet been too load...its just right so really happy with it. the sound is like daryls cutout but louder i found that the ecu must addapt to it because when i first put it on it was REALLY load all through the revs but now has calmed down a bit. the performance is about the same....torque and especially midrange there seems to be a bit more, up top about the same but at about 6k rpm it has the nicest note u will ever hear on an aurion so im sorry bondie my view is very different to yours and ill be out tonight with the brissy boys to see what they think im happy to take anyone for a drive if they want
